Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Ethyl-1-(4-fluorophenyl)-1,2-dihydrochromeno[2,3-c]pyrrole-3,9-dione.
CATO supplies 2-Ethyl-1-(4-fluorophenyl)-1,2-dihydrochromeno[2,3-c]pyrrole-3,9-dione (CAS 862209-62-9), a certified reference material (molecular formula C19H14FNO3, MW 323.32 g/mol) for analytical method development and quality control.
2-Ethyl-1-(4-fluorophenyl)-1,2-dihydrochromeno[2,3-c]pyrrole-3,9-dione (C19H14FNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
